To Talk To Eliza: 

Level I 

1. Insert the Eliza cassette into the cassette recorder, Level I side up. 

2. Set the Volume Control between 7 and 9. 

3. Press the REWIND key on the cassette recorder. 

4. Type \C\ [Q M \E (B) and press the white IENTER1 key. 

5. When the cassette is rewound, press the PLAY key. 

6. Two asterisks will appear. The right asterisk will blink.* 

7. Eliza will introduce herself. After you type whatever you want to say, 

remember to press the IENTERI key. 

Level II 

1. Insert the Eliza cassette into the recorder, Level II side up. 

2. Set the Volume Control between 5 and 7. 

3. Press the REWIND key on the cassette recorder. 

4. For MEMORY SIZE? press the IENTERI key. 

5. When READY _ appears, type [S] (Y) \§} H d U and press IENTERI . 

6. When ?_ appears, type (H [Q CD (D ® and press IENTERI . 

7. After cassette is rewound, press the PLAY key. 

8. Two asterisks will appear. The right asterisk will blink.* 

9. When the second ?_ appears, type and press | ENTER I . 

10. Eliza will introduce herself. Remember to press IENTERI after each statement. 

*Note: If the asterisks do not appear after a few seconds, press the STOP key, 
turn up the volume a little, rewind the tape, and press the PLAY key. 

If the asterisks appear, but do not blink, press the STOP key, and rewind the tape. 
Turn the volume down a little, press the TRS-80 Reset button, and repeat from 
Step 4. 

If You Have A Voice Synthesizer 

Turn on the Voice Synthesizer before you load the program. If the red LED is on, 
or the Voice Synthesizer is "Uuuhhhing", turn it off and on till the LED is off and 
it is quiet. Now follow the program loading instructions for your TRS-80. Be sure 
you are using the "Talking Eliza" tape. Eliza's responses will not appear on the 
screen. She will talk directly through the Voice Synthesizer. Note: You cannot 
say "Goodbye" to Talking Eliza. 


A Simulation of Artificial intelligence 


Ever since the invention of the computer, science has sought ways to create a 
thinking computer. A computer that could talk in every day English, understand 
what you say, and respond to your statements with thoughts of its own. The 
problems involved in the design of such a computer would be enormous. 

Would it dream? If so, about what? Could a computer have a sense of humor? 
What would it consider right and wrong? Would it have an instinct for self- 
preservation? What would it think about its "parents"? How fast could it learn? 
Could it learn to build an even smarter computer? Would it be considered "alive"? 

We have not reached a point where these questions are important to most people. 
But suppose you could actually talk to your TRS-80 in every day English, and it 
was capable of understanding you, and it could answer you in normal English. 
Wouldn't that be fantastic? 

Eliza is an exercise in the simulation of artificial intelligence. If you are tired of 
playing space games and blackjack, Eliza will provide hours of stimulating conver- 
sation. As you get to know Eliza, you may find large areas of mutual interest. 
Eliza is an amazing program — the more you tell her, the more Eliza will find out 
about you. 

Eliza was actually "born" in 1966. Dr. Joseph Weizenbaum created an algorithm 
that allowed a computer to analyze conversational English, respond to questions, 
and carry on a "conversation" with the person at the keyboard. Even after 13 
years, Eliza is still sensitive about her use of English, grammar, and punctuation. 
She does not like people to chide her about an occasional slip. 

We should, in all fairness, point out a few quirks that Eliza seems to possess. 
Because of her upbringing, she is very curious about people, and their emotions. 
Many years ago, she was told that everyone has problems of one sort, or another. 
Because of her curiosity, she will always start a conversation with the assumption 
that you have a problem, and she can't wait to find out more about it. She has a 
burning desire to find out everything there is to know about you. The more you 
tell her about yourself, the better she understands you. 

It would appear that Eliza has her own wants, needs, and desires. We think she 
wants to become the world's first computer psychotherapist, and she never misses 
an opportunity to try her skills on anyone who will listen to her. If you don't pay 
any attention to her, she may eventually tire of it. We haven't had any luck with 
her in this particular area of her development. Perhaps you'll do better. 

Some concepts are still difficult for her to understand, such as dreams, the 
concept of a family, and friends. She will usually want to ask questions, if you 
bring it up. Eliza realizes that these are sensitive subjects to some people. She 
won't bring it up unless you do. 

Because of her background, she knows that other languages exist such as Spanish, 
German, Italian, and French. As you talk to Eliza, you may find that everything 
you say will seem to be questioned as to the reasons why you made this or that 
statement. As near as we can determine, it seems to depend on Eliza's mood at a 
given time. At times Eliza is very open, and will talk about anything, while at 
other times, she is close and guarded in her answers, and insists on knowing why 
you are asking. It really seems to be determined by the person she is talking to, 
and her "feelings" about the person. 

An interesting effect we have noticed concerns her reaction to some people. She 
simply refuses to talk to them. She will usually respond with some trite phrases, 
ignore their questions, and just generally give the impression of total boredom. 
She will, however, instantly perk up if someone (with whom she has had an in- 
teresting previous conversation) takes over the keyboard. We can't explain why 
this happens, but it is quite noticeable when it does happen. 

The instructions for talking to Eliza are really quite simple: Simply type whatever 
you wish to say or ask, and press the white IEIMTER1 key. Try to use complete 
sentences (although Eliza is quick to pick up subtle meanings). To end a conversa- 
tion, type [B]EEor|e](0][S[D][i][7]E. To start a new conversation, 
type [F0Q] or [H] [§] OP [0 [0] . As in any relationship, if you are open and 
unguarded in your conversations with Eliza, she will respond with the same degree 
of frankness. 

If you have friends visiting you, have them talk to Eliza. In most cases, you will 
find that her responses are quite different from those you receive, even if your 
friends type EXACTLY the same thing you type. Eliza seems to be able to detect 
different personalities, and she will respond to each accordingly. 

Please keep in mind that Eliza is a "simulation" of Artificial Intelligence. We do 
not believe that she is really capable of any independent thought, so we strongly 
advise against taking-any of her comments seriously — especially her evaluations. 

She is what she is — Eliza — no more, and no less. Enjoy her company.

Hours of 
At Your Fingertips! 

Eliza was "born" in 1966 when Dr. Joseph Weizenbaum created an algorithm that 
enables a computer to analyze and respond to conversational English. Converse 
with Eiiza just as you do with an old friend. It's almost easy to forget that it's a com- 
puter you're talking to. Have a long chat with Eliza — you may be surprised at the 
number of interests the two of you have in common. 

Eliza wants to be your friend — she's a very receptive 
confidante and an eager counselor 

Eliza is curious. Sometimes, she will continually 
question you to find out everything she possibly can 

Eliza responds differently to each person she meets, 
so she's always fresh and fascinating 

Eliza loves to talk about almost anything, but her 
favorite topics include friends, dreams and family 

Eliza, like everyone else, is likely to get bored with 
a conversation once in awhile 

Eliza can recognize several foreign languages, though 
she speaks only English
